numrrii

Numrrii is a fictional numeral notation described in theoretical discussions of alternative numeral systems. It is not a real-world standard but serves as a thought experiment to explore how compact a numeral representation can be while remaining legible.

In Numrrii, a small set of base symbols expresses successive magnitudes, and higher values are constructed through a recursive composition rule that resembles nested exponentiation. Numbers are formed by combining symbols with simple operators that indicate multiplication of a base magnitude by fixed factors, together with delimiters that mark levels of hierarchy. The design goal is to encode very large integers with relatively few symbols, highlighting the trade-off between symbol economy and cognitive accessibility.

Numrrii appears in essays and speculative worldbuilding as an illustration of how numeral systems influence computation, communication, and mathematics education. It is often discussed alongside non-standard bases, non-positional notation, and notations for enormous numbers, to contrast efficiency with legibility.
